The odors basically fall into the following three categories.<\/h2>\n
The first category\u00a0principally\u00a0include methane and carbon dioxide.<\/p>\n
The second category includes malodorous gases such as H2<\/sub>S, NH3<\/sub>\u00a0and SO2<\/sub>. H2<\/sub>S is a kind of colorless toxic gas\u00a0with an irritating and asphyxiating smell. NH3<\/sub>\u00a0is extremely harmful to human\u00a0beings. SO2<\/sub>\u00a0is a colorless toxic gas with an irritating smell.<\/p>\n The third category are mainly\u00a0trace components, such as organic acids, sugars and compounds containing sulfur and nitrogen, which are highly toxic and pose a serious threat to human health.<\/p>\n Sodium humate deodorant is a product obtained by reacting such raw materials as peat, lignite or\u00a0leonardite\u00a0with sodium hydroxide. It is water-soluble and alkaline, containing active groups such as carboxyl groups and phenolic hydroxyl groups. Humic acid is a natural macromolecular organic compound which is generally considered to be a complex\u00a0hydroxybenzenecarboxylic acid compound with uneven\u00a0molecular weight\u00a0(having an average molecular weight between 1000 and 1400). Its main constituent elements are: C (carbon),\u00a0O\u00a0(oxygen), H\u00a0(hydrogen), N (nitrogen)\u00a0and S (sulfur).<\/p>\n From the viewpoint of the physical properties of humic acid, it has a colloidal property, which plays an\u00a0important role in its function as a deodorant. When electrolytes\u00a0are\u00a0added, the stability of the humic acid colloid is destroyed, its particles are flocculated to cause flocculation and precipitation, thus humic acid\u00a0is a kind of flocculant. Judged from\u00a0its chemical properties, humic acid is a kind of weak acid with complex macromolecular structure and various functional groups. It can be combined with pot\u00e1ssio<\/u><\/a>, sodium<\/a>, c\u00e1lcio<\/u><\/a>, magnesium<\/u><\/a>\u00a0or\u00a0ammonium to form corresponding humate. Humic acid\u00a0has a strong ion exchange capacity, thereby\u00a0being able to remove harmful heavy metal ions when it contacts\u00a0contaminants. It is particularly important that the humic acid molecules\u00a0contain benzene ring, fused ring and various heterocyclic rings, which are connected by bridged\u00a0bonds.\u00a0On those\u00a0rings\u00a0and their\u00a0branches, there are carboxyl groups, hydroxyl groups, methoxy groups and \u00a0amine groups, etc. Thus \u00e1cido h\u00famico<\/u><\/a>\u00a0has such properties as\u00a0acidity, hydrophilicity, ion-exchangeability; it also has strong complexation, chelating and adsorption capacity and thereby plays an important role in deodorization.<\/p>\n Listed below\u00a0are\u00a0the removal reaction processes\u00a0of humic acid as a deodorant for odorous substances such as ammonia, nitrogen, hydrogen sulfide and sulfur dioxide:<\/p>\n Ammonia usually comes in forms such as\u00a0NH3<\/sub>\u00a0and NH\/. Humic acid can react with \u00a0ammonia in the odor\u00a0and form an odor-free ammonium\u00a0and water-soluble salt.<\/p>\n NO\u00a0and NO2 <\/sub>\u00a0<\/sub>are\u00a0the most commonly-seen\u00a0air\u00a0pollutant in the form of nitrogen oxide.\u00a0NO2<\/sub>\u00a0is a kind of toxic corrosive gas\u00a0with an\u00a0irritating smell. After humic acid contacting and reacting NO2<\/sub>, <\/sub>the peptization\u00a0and absorption property of humic acid solution enables NO2<\/sub>\u00a0to be\u00a0dissolved in water and\u00a0form nitric acid and nitrous acid.<\/p>\n SO2<\/sub>\u00a0is a kind of colorless\u00a0toxic gas\u00a0with an irritating smell and good water solubility. Since humic acid deodorant has peptization\u00a0and adsorption property, its\u00a0deodorizing effect is better\u00a0after the contact of humic acid solution and SO2<\/sub>.<\/p>\n (1) The density\u00a0of H2<\/sub>S in a certain dumping ground is closely related to the composition of the dump. If\u00a0there is a large amount of organic matters\u00a0in the dump, H2<\/sub>S will increase greatly when they decay. Sodium humate solution can react with H2<\/sub>S and\u00a0remove the odor.<\/p>\n (2) Removal of hydrogen sulfide by the absorption property of humic acid: humate can be\u00a0hydrolyzed in water\u00a0and\u00a0forms\u00a0a humic acid gel.\u00a0Humic acid reacts with iron ions in the garbage and\u00a0form a kind of humic acid iron salt (colloidal spongy\u00a0iron). Then hydrogen sulfide reacts with hydrated humic acid\u00a0iron\u00a0and\u00a0forms\u00a0humic acid and insoluble iron sulfide. Humic acid and some metal ions can not only form salts, but also form compound or chelate through reaction between the oxygen-containing functional groups on its\u00a0side chains and bivalent and polyvalent metal ions such as Cu”‘, Hg2+, Cd2+, Fe3+, Ge4+, U”. As long as H2<\/sub>S is present in the waste, when the above-mentioned metal ions\u00a0contact with\u00a0hydrogen sulfide, they\u00a0will quickly combine into a insoluble sulfide precipitate, which quickly and thoroughly removes harmful hydrogen sulfide gas\u00a0and it odor.<\/p>\n Organic acids, sugars and compounds containing sulfur and nitrogen are produced during the decomposition process\u00a0of organic matters\u00a0in the waste. These substances have certain reactive groups and they are easily complexed or chelated with such metal ions as Fe3+\u00a0or\u00a0Mi. Humic acid, which contains\u00a0aromatic structures and carboxyl groups, is a\u00a0good chelating\u00a0agents. Humic acid is capable of capturing metal ions due to its negative chargeability on\u00a0its primary functional groups. In order to maintain the ionization equilibrium, the insoluble metal compound will be continuously dissociated, so that the metal may be converted from poorly soluble compounds\u00a0to humates, coordination\u00a0compounds\u00a0or chelates, thereby removing the odors\u00a0emitted by\u00a0organic acids, sugars and sulfur- and nitrogen-containing heterocyclic compounds which are produced\u00a0during the decomposition process of\u00a0the garbage.<\/p>\n In addition, the humic acid content in sodium humate\u00a0solution is a kind of nutrient-rich\u00a0microbial nutritional medium. It is a beneficial bacterial population, containing\u00a0beneficial microorganisms such as yeast, lactic acid bacteria, photosynthetic bacteria, and actinomycetes. Thus the\u00a0beneficial microbial liquid plays\u00a0a key role in removing pollutants. As long as the beneficial microbial population\u00a0is activated, it plays an important role in the treatment of various pollutions.<\/p>\n <\/p>\n Escrito por\u00a0H\u00famico<\/u><\/a>\u00a0| Organic Fertilizer Manufacturer<\/u><\/a> With a growing amount of\u00a0wastes\u00a0caused by human activities, various odors appear in such places as garbage dumps, toilets, animal farms\u00a0and slaughterhouses\u00a0and\u00a0thus\u00a0seriously pollute the environment. In today’s society,\u00a0which greatly values the environment, it becomes rather urgent to solve the problem of how to effectively and quickly deodorize those fore-mentioned\u00a0odor sources.
